white square artifact on finished render

[jonlo84]

im getting a strange white square artifact on the eye after the rendering is done.  all the settings are on default.  im doing a network render with 3 other computers and denoise enabled with 10 passes.  the eye material has reflection set to 1. (default settings.)

Hi. If you're talking about the white square in the black pupils, then it looks like a regular reflection of a square light plane.

Is that the case? If not, then please give some more details about the scene/light setup.

Regards

i have 3 lights, corona lights.  two spheres and 1 rectangle, which i guess thats where the white square is coming from.  i was expecting a circular highlight.

i got it figured out, thank you.  i didnt know that the reflections from the lights were going to be that apparent.

The theme of the image obliges me to explain things:
Corona is physically-correct, which means that if a light is rectangular, then its reflection will be rectangular too. You can however disable the reflections/refraction of a light while leaving its illumination by unchecking the desired checkboxes in its settings.
